Uhlelo noma usebenzise i-Excel? Kungani uyeka ukusebenzisa amaspredishithi

Amaspredishithi ayithuluzi elidumile lokuphatha nokubala inani elikhulu lemininingwane. Noma kunjalo, inketho engcono kungaba ukusebenzisa ulimi lohlelo Julia.

Ngo-2010, osomnotho ababili abahlonishwayo baseHarvard University, uCarmen Reinhart noKenneth Rogoff bashicilela izindatshana ezimbili ezazisetshenziswa umhlaba wonke ngabezombusazwe ukuxhasa izinhlelo zokuqina.

UReinhardt noRogoff bathi ukukhula komnotho okujwayelekile kwehla (kwehla ngo-0,1%) lapho isikweletu sezwe sikhuphukela ngaphezu kwama-90% womkhiqizo wasekhaya omningi (GDP). Kodwa-ke, lapho besebenzisa iMicrosoft Excel benze iphutha elilula elinemiphumela emibi.

Izazi zezomnotho azikhethanga wonke umugqa lapho kulinganiswa izibalo zokukhula - bayishiya imininingwane kusuka e-Australia, e-Austria, eBelgium, eCanada naseDenmark. Ngokwengeza la mazwe, ukuncipha kuka-0,1% kuphenduke ukwanda okuphakathi kuka-0,2% ekukhuleni komnotho.

Ngokuvamile, amaspredishithi anezinkinga ezintathu:

• Abavumeli ukuqinisekiswa okuzenzakalelayo nokuhlelekile kwedatha etholakalayo.
• Indlela imininingwane ethulwa ngayo yenza kube nzima kakhulu kubantu besithathu ukuthola amaphutha.
• Bakhuthaza isimilo sokusebenza. Kwesinye isikhathi ukonga amafomula wesikhathi kukopishwa futhi kunamathiselwe lapho kufanele kwenziwe khona ukulungiswa, abakhohlwa ukukwenza.

Mhlawumbe ngoba ukudala uhlelo oluthile kukuphoqa ukuthi unake kakhulu okwenzayo noma, ngoba banokuhlukahluka kunamafomula ahlelwe ngaphambilini ukuthi amaspredishithi awahlinzeki, iqiniso ukuthi izilimi eziningi zemithombo evulekile zisetshenziswa kakhulu kwezomnotho.

Uhlelo noma usebenzise i-Excel? Kungani uJulia angcono kune-Excel

Ulimi lohlelo lweJulia seluhlale ngokusemthethweni iminyaka emibili. Uhlobo lwayo 1.0 lwashicilelwa ngo-Agasti 2018, ngemuva kweminyaka eyishumi yentuthuko. Lezo zinyanga ezingamashumi amabili nane zazanele ukulenza libe ngelinye lamathuluzi aphambili okuhlaziywa kwedatha.

UJulia ungumthombo ovulekile, ulimi oluhlelayo lohlobo olunamandla. Yize ingasetshenziselwa izinhlelo ezijwayelekile, yaklanywa ngezidingo zabasebenzisi bekhompyutha besayensi nabamanani. UJulia usekela ukufana okuphuma ebhokisini, enikela ngamazinga amathathu abalulekile wokufana ahlukaniswa njengoJulia coroutines, afundwe ama-multithread (okwamanje ahlolwayo), kanye ne-multicore noma ukusatshalaliswa okusabalalisiwe.

Izilimi zohlobo lweDynamic yilezo ezivumela ukuguqulwa kwenziwe ngenkathi uhlelo lusebenza.

Ngokufana sisho indlela yokuxazulula izinkinga ekhompyutheni equkethe ukuhlukanisa izinkinga ezinkulu zibe yizincane eziningana nokuzixazulula ngokufana.

Ezinye izinzuzo zikaJulia ngaphezulu kwe-Excel

• Kungumthombo ovulekile, ngakho-ke akudingeki ukhokhe amalayisense abizayo ukuze uyisebenzise.
• Isekela ukusetshenziswa nohlelo lokulawula inguqulo, okuvumela ukubuyekezwa kontanga komsebenzi owenziwayo.
• Kuyi-multiplatform; itholakala ngemishini ye-Windows, Mac, Linux, FreeBSD, ne-Docker.
• Akunasidingo sokuya kolunye ulimi lohlelo. Uma umsebenzisi edinga ukudala imitapo yolwazi emisha, angakwenza ngokuphelele eJulia. Ku-Excel kuyadingeka ukuthi usebenzise ulimi olukhulu)
• Ukusebenza okuphezulu. UJulia wenzelwe ukubala ngokushesha.

Vele kunezinye izinto okufanele uzicabangele. Ezindaweni eziningi umsebenzisi akakwazi ukunquma ukuthi uzosebenzisani. Ngisho noma ngabe iyiphi ikhompyutha ye-Windows isekela uhlelo noJulia, kungenzeka ukuthi kuzofanele wabelane ngaleyo datha nabanye abantu abenqabayo ukuyeka ukusebenzisa i-Excel. Kodwa-ke, uJulia unemitapo yolwazi ekuvumela ukuthi ungenise futhi uthumele idatha ku-Excel.

Okwesibili ijika lokufunda. Akufani ukuqedela idatha kumsizi kunokwenza uhlelo. Ukungasho ukuthi kunemibhalo eminingi kakhulu yokwenza okuthile ku-Excel kunakuJulia.

Nanamuhla, amakolishi namanyuvesi aqhubeka nokufundisa ukusetshenziswa kwe-Excel ukubalwa kwebhizinisi kanye nezinhlelo njengesihloko esivela ngaphandle. Ngokusetshenziswa kwezilimi ezinjengoJulia, abafundi ngeke nje banikezwe umuzwa wobuqotho kulokho abakufundayo. Bazophinde balungele kangcono umhlaba lapho ukutolikwa kwedatha kuzoba yikhono elibucayi.
